Abstract: A method performed by an apparatus is presented which comprises determining one or more potential installation positions and/or areas for installing one or more radio positioning support devices in a predetermined environment, wherein said one or more potential installation positions and/or areas are determined at least partially based on at least one radio coverage model.

Abstract: An apparatus obtains test data, which comprises radio samples with associated indications of reference locations. The apparatus estimates for each of a plurality of representations of a radio environment positions based on the radio samples of the test data and on the respective representation. Each representation has been generated based on a different selection of batches of fmgerprints. Each fmgerprint comprises a radio sample and an indication of a location of measurement. Each radio sample includes a characteristic of a radio signal transmitted by at least one beacon and an identification of the respective beacon. The apparatus determines for each representation a positioning performance by comparing the estimated positions with the reference locations. Based on the determined positioning performances, the apparatus determines whether any batch of fmgerprints is to be excluded from further use and/or which representation is to be used as a valid representation of the radio environment.

Abstract: A system obtains information on positions stored for a communication node and criteria that are met by the node. The system selects a-priori information on a coverage area size that is stored for nodes meeting the criteria. Different a-priori information is stored for nodes meeting different criteria. The system estimates a value of at least one parameter representing a coverage area of the node based on the information on the positions and the selected a-priori information. The value of the at least one parameter is stored. For generating the a-priori information, the system may extract from a memory information indicating a size of a coverage area for each of a plurality of communication nodes, compute a statistical value based on information indicating a size of a coverage area that is extracted for a plurality of nodes meeting the same criteria, and provide the computed statistical value as a-priori information.

Abstract: Method, apparatus, and computer program product example embodiments are disclosed for improving the speed and sensitivity of position determination by wireless communication devices using assisted Global Navigation Satellite Systems (A-GNSS). Example embodiments include multi-SIM mobile wireless devices having an A-GNSS location detection capability, with one or more RF modems that may communicate with one or more wireless carriers.
